I've got the 4 link covered...no worries about that.
Just not sure of any benefit to switching from coil on axle with a separate shock to a coilover behind the axle.
I can easily straighten up the shocks and already have the adjustable shocks on it, no need for ride height adjustment since it sits where I want it now.
I'm only asking about any ride comfort or handling benefit to the coilover vs coil spring.
